The Se7en Wetlands property was previously utilized for phosphate mining prior to the construction of the system.

Thus, the Cargill ditch likely conveys nutrient rich flow resulting from legacy phosphorus and is thought to be one contributing factor in the occurrence of HABs within the treatment wetland …
